Granite Countertop Cost & Installation Factors

National cost guides put a typical granite countertop project at roughly $2,000 to $5,000, with averages around $3,250 to $3,500. The slab itself usually runs about $40 to $60 per square foot for common stones, and $200 or more for rare ones. On top of the slab, your final price depends on how much stone you need and how it's fabricated: the edge profile, sink and cooktop cutouts, the finish, and the installation itself.

These are national estimates from different publishers, each with its own assumptions. They are not local prices and not Mega Solutions prices. This guide explains what each number covers, what moves it up or down, and what to ask before you choose a slab.

Material Cost vs. Installed Cost

Granite prices are quoted in two very different ways, and mixing them up is the most common source of confusion:

• Material cost: the price of the slab, per square foot, before anything is cut
• Installed cost: the whole project, meaning the slab plus templating, fabrication (cutting, edges and cutouts) and installation

Fixr's own examples show how wide the spread can be. Its low end, about $750, is 30 square feet of granite tile in a common stone. Its high end, about $8,000, is the same 30 square feet in an exotic stone with a custom edge, two sink cutouts and an undermounted cooktop.

Slab Price: Grade, Color and Rarity

The slab is the biggest variable. HomeAdvisor puts most granite material at $40 to $60 per square foot. Fixr gives a wider $40 to $200, with a few exotic stones up to $400. The difference comes down to how common the stone is.

Fabricators often group slabs into price levels. Some number them 1 to 4; others use names like builder-grade, premium and designer. The labels vary from shop to shop, but Fixr's ranges give a sense of the spread:

Color affects price too, mainly because some colors are rarer. HomeAdvisor notes that darker granites often cost more than lighter ones. In Fixr's color averages, blue stones are the most expensive and gray the least, but every color group runs from inexpensive to exotic. The same stone can also be sold under different names, so compare the actual slab rather than the name on the tag.

Slab, Modular or Tile

Most kitchens use full slabs, but there are cheaper forms of granite:

Fabrication: Edges, Finishes and Cutouts

Edge profile

Every exposed edge has to be finished. Fixr says an eased or square edge usually adds nothing, while decorative profiles are charged per linear foot of edge:

Edge costs add up on an island, which has exposed edges on several sides.

Surface finish

Polished is the standard finish and costs nothing extra. Both Fixr and HomeAdvisor put a honed (matte) finish at about $10 to $20 more per square foot, and a leathered (textured) finish at about $15 to $25 more. Not every stone can be honed or leathered, so ask before you set your heart on a finish.

Cutouts

Both guides put a sink cutout at about $100 each and a cooktop cutout at about $200. Faucet holes and outlet cutouts may be priced separately or included, so ask how your quote handles them.

Installation and Other Costs

A few more things can affect the total:

• Plumbing: the sink and faucet need to be disconnected and reconnected. HomeAdvisor notes this may mean a plumber's fee.
• Cabinet support: granite is heavy, and HomeAdvisor notes cabinets may need reinforcement to carry the weight.
• Access: Fixr notes that very large pieces and hard-to-reach areas, such as upper floors, raise installation cost.
• Slab size and seams: Fixr puts the average slab at roughly 8 by 10 feet. A large island or long runs may need a seam or a second slab, which adds material and labor.

How Granite Installation Works, and Why It Affects Cost

1. 1Choose your slab. With full slabs, you can usually see and reserve (tag) the exact slab. Fixr recommends doing this, since color and veining vary from slab to slab.
2. 2Templating. The countertops are measured after the base cabinets are installed. Have your sink, faucet and cooktop details ready, because the cutouts are made to fit them.
3. 3Fabrication. The slab is cut, edged and polished. Fixr puts the time from templating to installation at about 2 to 3 weeks.
4. 4Installation. The pieces are set and secured, and seams are filled with color-matched epoxy. Fixr notes the sink plumbing is often reconnected about a day later, once the adhesive has cured.

Because templating waits for the cabinets, plan cabinets and countertops on one schedule if you're replacing both. Our guide to kitchen cabinet installation cost in Atlanta covers the cabinet side, and the countertop installation process walks through each step.

Ways to Manage Your Granite Budget

• Start with common stones. Builder-grade granites are the most affordable and often consistent from slab to slab.
• Keep the standard edge and polished finish. These usually add nothing; decorative edges and honed or leathered finishes do.
• Use remnants for small areas. Leftover pieces can be a low-cost way to get granite on a vanity or small counter.
• Keep the layout simple. Fewer corners, cutouts and seams mean less fabrication.
• Compare whole quotes, not price per square foot. One quote may include removal, sealing, cutouts and backsplash while another doesn't.

What a Granite Quote Should Include

• the specific stone, its level or grade, and its thickness
• the square footage, and whether it's measured from a template
• the edge profile and how many linear feet are being edged
• the number of sink, cooktop, faucet and outlet cutouts
• any backsplash
• installation, including how seams will be placed
• removal and disposal of the old countertops
• sealing, if the stone needs it
• who disconnects and reconnects the sink and faucet
• the expected timeline from templating to installation
